Stenocarpella spp. causes stalk and ear rot in maize and overwinters in stubble during
the off-season. Understanding the factors that guide saprophytic colonization is a crucial strategy
for management. In this study, we analyzed the abiotic factors and crop management practices
in relation to the inoculum of Stenocarpella spp. in stubble by qPCR. Soil samples were used for
suppressiveness tests against Fusarium verticillioides, Fusarium graminearum, and Stenocarpella maydis.
In the 29 fields, different levels of Stenocarpella spp. were detected. Only three fields were considered
suppressive for the three pathogens. Heat maps showed that soil suppressiveness was inversely
related to the pathogen concentration, and the suppressiveness of one pathogen was correlated with
the suppressiveness of other pathogens. Under no-tillage systems in which rotation with soybeans
was adopted, Stenocarpella spp. were detected at lower concentrations than in areas that adopted
notillage systems with maize monocultures. While in tillage systems, the maize?maize monocropping
increases the inoculum level of Stenocarpella spp. Crop rotation is a factor related to the observed
reduction in the pathogen concentration and increases in the broad-spectrum antagonistic microbial
communities. These communities guide the suppressiveness of soil-borne diseases in maize fields
cultivated under tropical conditions. |
